a. 802.1p

Select this option to Activate/Deactivated the 802.1p IEEE 802.1p establishes eight levels of

priority (0 ~ 7). Although network managers must determine actual mappings, IEEE has

made broad recommendations. Seven is the highest priority which is usually assigned to

network-critical traffic such as Routing Information Protocol (RIP) and Open Shortest Path

First (OSPF) table updates. Five and six are often for delay-sensitive applications such as

interactive video and voice. Data classes four through one range from controlled-load

applications such as streaming multimedia and business-critical traffic - carrying SAP data,

for instance - down to "loss eligible" traffic. Zero is used as a best-effort default priority,

invoked automatically when no other value has been set.
